Abstract
The invention discloses a double-hydraulic-control single rod type hydraulic cylinder which comprises a cylinder sleeve, an independent piston, a lower oil port, a piston rod and an upper oil port. The independent piston is located in the cylinder sleeve. The lower oil port is located in the bottom end of the cylinder sleeve. The upper oil port is located in the center of the piston rod. One end of the piston rod is slidably connected with the cylinder sleeve. By the adoption of the double-hydraulic-control single rod type hydraulic cylinder, a chassis of a vehicle can be heightened rapidly, and the passing capacity and reliability of the vehicle are improved.
Description
Technical field
The present invention relates to a kind of hydro-cylinder, particularly relate to a kind of double hydraulic control single lever-type hydro-cylinder.
Background technology
The chassis elevating function of modern high end automobile mainly utilizes the air capacity to pneumatic cushioning and pressure to regulate, thus reaches the object of chassis lifting. But mix realization substantially with anti-vibration function, in motion, the reliability of its height just is difficult to ensure, and ageing due to what inflate, and the amplitude of general lifting is little, maximum tens centimetres.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of double hydraulic control single lever-type hydro-cylinder, its rapid lifting vehicle chassis height, it is to increase vehicle by property and reliability.
The present invention is solved the problems of the technologies described above by following technical proposals: a kind of double hydraulic control single lever-type hydro-cylinder, it is characterized in that, it comprises cylinder sleeve, stand alone type piston, Xia Youkou, piston rod, oil mouth, stand alone type piston is positioned at cylinder sleeve, lower oil mouth is positioned at the bottom of cylinder sleeve, the mouth that oils is positioned at the center of piston rod, and one end and the cylinder sleeve of piston rod are slidably connected.
Preferably, described lower oil mouth and the mouth that oils are all oil inlet and outlets.
Preferably, the oiling amount of described lower oil mouth determines the height of stand alone type piston.
Preferably, oil described in the oiling amount decision piston rod of mouth and the relative height of stand alone type piston.
Preferably, the diameter of one end of described piston rod is greater than the diameter of the other end of piston rod.
Preferably, described stand alone type piston can slide up and down in cylinder sleeve, and the top and the bottom of stand alone type piston are oil chamber.
Preferably, the piston of described piston rod and stand alone type piston are all equipped with tightness system.
The positive progressive effect of the present invention is: the present invention rapid lifting vehicle chassis height, it is to increase vehicle by property and reliability.
Accompanying drawing explanation
Fig. 1 is the structural representation of double hydraulic control single lever-type hydro-cylinder of the present invention.
Embodiment
The better embodiment of the present invention is provided, so that the technical scheme of the present invention to be described in detail below in conjunction with accompanying drawing.
As shown in Figure 1, double hydraulic control single lever-type hydro-cylinder of the present invention comprises cylinder sleeve 1, stand alone type piston 2, lower oil mouth 3, piston rod 4, oil mouth 5, stand alone type piston 2 is positioned at cylinder sleeve 1, lower oil mouth 3 is positioned at the bottom of cylinder sleeve 1, the mouth 5 that oils is positioned at the center of piston rod 4, and one end and the cylinder sleeve 1 of piston rod 4 are slidably connected. Lower oil mouth 3 and the mouth 5 that oils are all oil inlet and outlets. The diameter of one end of piston rod 4 is greater than the diameter of the other end of piston rod 4. The piston of described piston rod and stand alone type piston are all equipped with tightness system. Stand alone type piston can slide up and down in cylinder sleeve, and the top and the bottom of stand alone type piston are oil chamber. Piston rod is open core type piston rod.
The oiling amount of lower oil mouth determines the height of stand alone type piston, and the oiling amount of the mouth that oils determines the relative height of piston rod with stand alone type piston, is also exactly oil the oiling amount of mouth and the oiling amount of lower oil mouth determines the height of piston rod jointly. The change (can not often change) of lower oil mouth oiling amount can promote the change of stand alone type piston position, also just changes the basis of piston rod, thus changes vehicle chassis height, provides technical support for obtaining fast rising or falling speed and amplitude. And mouthful change for oiling amount that oils is dynamic, it is go to change by the control overflow of anti-vibration.
If double hydraulic control single lever-type hydro-cylinder of the present invention all installed by all wheels, under the control of corresponding hydraulic pressure, can lifting vehicle chassis height within the specific limits, it is to increase vehicle by property, and can provide a kind of possible for the height of dynamic adjustments anti-vibration and soft durometer.
Above-described specific embodiment; the technical problem of the solution of the present invention, technical scheme and useful effect have been further described; it is it should be understood that; the foregoing is only specific embodiments of the invention; it is not limited to the present invention; within the spirit and principles in the present invention all, any amendment of making, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
